To all zit may concer/ti' y l 'Be it known that I, BENJAMIN F. BERRY,

a resident of the city of St. Louis, 1n the VState of Missouri, have mvented certain newfand. useful Improvements in `FeedA Tables for Presses and the like, of which the followiupr is, a full, clear, and' exact description, re ereuce being had to the accompanying drawings," forming a part of this specification. ,Myiiinvention relates lto improvementsv in feed tables for-'presses and the like, and is especill'asuseful' as applied to :printmg presses capable of handling sheets of 'large size. lit present yit 'is dii'cu-lt to handle large sheets of this' character for they a're not only heavyto li-ft ontojthe work Atable inhundles',v

but it lis also-diflicult to pick off the top s heet 'of the' stack andfeed it. into the. press from' -ffthe table. My inventioncontemplates the' 'use of a vertically movable platform which may be lowered ontothe `floor where itmayeapex' stock'to be print. ed and,- then` hoiste "automatically intolits l.

properposition forhandling.

f itnotherlobject ofmyginvention 1s to automatically separate or comb the top sheets4 ,-.otbe stackzfrom the stack proper, so that.

#theo erator, may have 'single sheets at hand sheet' from the remainder of the stack when ,this 'is donefby hand, .es ecially'when 'fthe y table 2, parallel to the guide rodsfy9' so that sheets' are large :and are o' thin' paper. stock. .Myn invention' provides for y sheet "separators'acting 'in conjunction with the automatically movin stack-lifting mechanism, which combers s all project the top sheets forwardly'o the Astack toward the work table Wherefthe'operatw may easil feed singlel sheets vintov the press, the stac lifting-mechanism being so designed that it and illustratedin theia'ccompanying drawings wherein is shown, the

j Sup ortedjbyl 'the frame '4 is, a yertically, movab e sup rlfyplatorm 7, said'platform v beingy pivote y secured' at one 'end 8 to: verl.

tical gu1des 9 so that it is freejto m`ove verA tically, said guides being positioned 'atthe lower end of the inclined piatform. The

`platform 7 isadapted toreceive a vstack of sheets B, which are to be raised vertically and fediuto the press (not shown);

-Aserles'of T-'rons 10 are secured tothey they form a plane guide for the stackv of sheets. The upper ends 1l 'of thedronsl are bent back toward theftable` 2' so este `guide .the sheets onto the/table as they pass these bent ends 11.V I The supply plati'orn'i- 7 is lifted byv actuat7 ing mechanism mounted on the frame 4,"said mechanlsm'comprisin'g a 1notor12,.driv in'g through 'reduction gearing, .a pair o 'worms, 4' .13 and 14, one at each end of the drivesliaft l5. the frame 4 so as to mesh with the *worms 13 and 14, respectively. Each of. the"'gear wheels 16 and 17 :drivesa 'pair of'windin rdrums 18 and '19, respectively, throng icov Gear wheels 16 and 17 -aie mountedlon "los shafts 20 and 21', respectively,'secured vto the gear Wheels 16 and 1 7, respectively. *Pairs and 19, respectively,

i used; that is` highly calender-ed sheets Will require a lesser angle ot tilt than rough cardboard or matted sheets. rl`l1e adjustn'icnt yoit the tilting angle is obtained hy disconnect ing a pair of winding drums troni the driv ing mechanism and then actuating the other pair of drums to lift the platform. This will tilt the platform about its pivot 8.

v The means for effecting the tilting of the platform comprises a clutch mounted on the frame /land interposed on the-shaft 15 between the worms 13 `and lll,y the shaft l5 beingI divided into two Sections for that purpose. .The clutch 25 is operated bymeans of a handle 25 positioned so yasto be conveulent toy the operator. When the clutch'V is thrown out, it disengages the worin 1l n' from the driving connection with the motor l2, andthe entire'drive is therefore. transi mitted through the worm 13 and drums lll,

the 'drums 19 remainingr idle. Thus it is 'seen that when the .motor is operating and the clutch 25 is thrown-so that the worm lil is inoperative, ythe platform will tilt about cured to the upright members 5 of the traine v its pivot 8. l u

In order that the sheets may he delivered 'singl onto the'work table 2, there are provide( comhingor sheet-separating' .means, also mountedupo-n the ,traine 4, said separating or combing means .being mounted below the .transverse tierod 6 and adapted to slide along the-- vertical' guideways 2l' se* 4. 'A transverse har'28.is supported `hy the frame 4 and this hart-supports the combing apparatus, said apparatus comprising a pair of delectors ZQeDgageahle with the top cor ner of the stack of sheetsso as to project the sheetsforwardlyin the direction ot' the Work table, and a pair otserrated friction rollers 30, said rollers heing driven hy means of a motor 31 mounted iipon the transverse bar 2S. i i

.The entire combing apparatus comprising Vthe friction rollers, deflectors-and motor 31 can be adjusted Ivertically or horizontally, the vertical adjustment being effected hy providing threadedguide extensions 32 at the ends of the bar 28, saidguide extensions being adapted to slide inthe guideways 2?' and being threadedly mounted upon rods 83 secured tothe tie) rod 6.- The upper ends or" the threaded rods 33 have beveled gears 34. adapted to mesh with beveled gears 35, the beveled gears 35 heilig rotatahle by Ameans of an adjusting handle 86. The horimotor l2 will actuae. the hoisting means to litt the supplyplatorm with the stack of sheets.a so that the top portion of the stack is projected forwardly toward the work tahle hy means of the detlcctorsQQ. meanwhile permitting the friction rollers 30 to contact with successive top sheets of the stack. The platform 7 and the stack of sheets is lioing continually lifted during the operation ol the device, so that there will always he presented new top sheets to the friction rollers 30, and as these friction rollers 30 are positively driven they will tend to move the top sheets forwardly onto the table Q. Y

(looperating with the combing means and mounted on jthe stationary table 2 are a series of traveling 'conveyors 39,4 said conveyors being driven hy means of' the motor l2 through a worm t() which drives a gear wheel 41, said gear wheel having secured thereto, a. sprocket 42. A sprocket chain 43 is driven hy the sprocket 42 and drives at its other end a. sprocket 44. whichV in turn drives a shaft 45 to wliiclrtlie series of conveyors are connected.

As it is not necessary nor desirable that Athe sheets upon the conveyor he. disturbedv ,when the supply platform is lowered, there is provided in the driving connection to the conveyors means which will cause the travcling conveyors to travel only in one` direction and allow them to remain stationary when the sprocket is rotated in the opposite direction. rlhis driving connection consistsot a pawl and ratchet shownin Fig. V. "hen the sprocket is driven in one direction. the pawl 4G will engage the ratchet 47 to drive Athe shaft 45, hut when the sprocket is rotated in the opposite directiomthepawl lo will move idly on the ratchet t7 and thus will not transmit any motion to the convovor shaft 45.

erator may then `feed themsingly intot e press. I

The 'conveyors are so geaaed that they liso ` even 'though' the sheets 'are Lea-e376 E travel at a higher surface speed than the combers so that they will tend to pull the lsheets away romlthe platform and thus' separate or single them out from'the stack.

.()Win to the inclinationo the platform 7, the sheets tend to slide downwardlyand very large'and comparatively thin, orl rough, they can be very easily forced downwardly romthe top of the inclined'stack. The inclination of the platform 7 can be varied :to obtain.thel
